SPECIFICATION formingpart of Letters Patent No. 364,460, dated June 7,1887. Applicaiio'n filed February 2, 1887. Serial No. 226 274. (Nomodel.)

' To all whom it may concern:

Be it known that I, JOHN MVABBOTT, of Silver Plume, in. the county ofClear Creek and State of Colorado, have invented a new and ImprovedSchool-Desk, of which the following is a full, clear, and exactdescription.

This invention relates to a novel form of desk wherein the parts are soarranged that the writingleaf or desk proper may be folded back out ofthe way, a proper receptacle being arrange' for the scholars booksat oneside of the seat, a novel form of ink-well being arranged in connectionwith the folding leaf which at times constitutes the scholar-s desk, allas will be hereinafter more fully explained.

Reference is to be had to the accompanying drawings, forming, part ofthis specification,

in which similar figures of reference indicate corresponding parts inall the views.

Figure l is aside view .of my improved form of desk, the parts beingrepresented as they appear when the leaf which at times constitutes thedesk proper is folded back, so that it rests in a perpendicular plane atone side of the chair, the position to which the leaf is moved priorto-being turned down to a horizontal plane being indicated in dottedlines, Fig. 2 is a face view of the novel form of desk, the parts beingrepresented in the position in which they are shown in Fig. 1. Fig. 3 isa side view representing the desk as it appears when arranged for use.Fig. 4 is a sectional view taken on line :0 so of Fig. 3. Fig. dis asectional view of the ink-weli. Fig. 6 is a ilan view of the desk, andFl 7 isa view taken upon the line y y of Fig.3.

In the drawings, 10 represents a standard, preferably of metal, uponwhich. there is mounted a seat or chair, 11, having a back, 12. To theright-hand side of the seat 11 there is secured a box, 13, having a lidor cover, 14.

Just in advance of the box 13 there is so cured a bracket, 15, formedwith two or more upwardly-extending lugs, 16, and with shoulders 2, asbest shown in Fig. 4. To the bracket 15 there is connected a swingingblock, 17, said block being formed with downward]y er:- tendingprojections 3, that are centrally re-' ccssed to receivctheupwardly-extending lugs 01' projections 16, the projections 3 and 16 being cpertnrcd to receive a pin erlpintle, 18',

so that the block 17 is free to swing upon the bracket 15, all motion inthe direction of the arrow shown in Fig. 4 being limited by reason. ofthe engagement .of the lower ends of the projections 3 with theshoulders 2 tha t-are formed in connection with the lugs or projec- Itions 16. The block 17 is also formed with outwardly-extendingprojections 4, to'which projections there is connected aleaf-snstainingarm or bracket, 19, said arm or bracket being 1 formed with projections5, that rest upon the projections 4, the said projections 4 and 5 beiingunited by pivot pins or pintles, as indi- .eated in Fig. 3.

, The leaf 20, which constitutes the desk when folded to the position inwhich the parts'are shown in' Figs. 3"and 4, is connected many suitablemanner to the supporting arm or bracket 19,which-arm is itself made upof the main portion 6, to which the desk or lcafis secured, and with anauxiliary arm, 7, a brace,

8, extending forward from the arm 7 to the main portion of thesu-pportingarni 19.

A catch, 22, is pivotally connected to 'a bracket, 23, and the heel ofthis catch is normall y forced away from thisleaf20 by a spring;

24. 'This catch 22 and a toe, 9, that is formed upon the bracket 23, arearranged to pass through an aperture, 26, that is formed in the, block17, the catch 22 serving, when in engagement with the bloek- 17, topreventlthc leaf 20 from swinging upon its pivotal connection with theblock 17, while the toe 9 of the bracket serves to strengthen andstiffen the connection between the parts. v

To the outer face of the block 17 there, is socnred a sliding block, 27,which is held to the block 17 by pins or bolts 28 that pass through along slot formed iu the block 27. The upper end of this block 27 extendsoutward and into the path of the heel of the catch 22, as shown at 29. f

Eroin the construction described it will be seen that the leaf 20 may bemoved'from the position in which it is shown in full lines in f Fig. 1to the position in which it is showlrin dotted lines in saidfignre,swinging at this time '7- upon the pins or pintles which passthrough the brackets 4 and 5. Then from the position in which the leafis shown in dotted linesin Fig. 1 may be moved downward, soas. to restin a horizontal plane, the too 9 audTF-the IOO,

catch 22 passing through theaperture 26 as the leaf approaches ahorizontal plane, all movement of the parts beyond that required tocarry the leaf 20 to the position shown in Figs. 3 and 4 beingprevented, owing to the engagement of the projections3 with the stops orshoulders 2.

As the parts are moved to the position in which thcyare shown in Fig. 4cthe spring 24 will act to throw the catch 22 into engage ment with theblock 17; but when the leaf 20 is moved back to the position shown indotted lines in Figsrl and 2 the heel of the catch will strike again'stthe sliding block 27,aud as said block strikes against the lugs orshoulders 2 it will be forced'in the direction of the arrow shown at ain Fig. 4, and the catch 22 the forward left-hand corner of the leaf.

will be freed from engagement with the block 17, the constructiondescribed providing for.

the automatic locking and unlocking of the" an aperture formed in theleaf 20, the well being adjusted so that the tube shall be "toward thisway, "as the leaf is moved to the position in'whieh it isshown indot-ted lines in Fig. 1,

the ink would be below the tube, and when the leaf is moved to theposition shown in full lines in Fig. 1 ilI'WOllld still be. below thetube.

,It will be understood that the aperture 32 does not extend to the topof the well 30, so that when ink is supplied, to the well it will notfill the entire cavity, owing to the resistance of the airconfined abovethe aperture 32. v

Having thus fully described my invention, I

claim as new and desire to secure by Letters Patent- 1. The combination,of the vertical supporting bracket 15, the vertically f swingingWitnesses:

the arm 19 and having on its under side a catch,

22, to enter the aperture 26 when the leaf and its arm are swunghorizontally into position, substantially as set forth.

2. The combination, with the vertical supporting-bracket 15 and thevertically-swinging block 17, pivotally connected at its lower edge tothe upper edge of the said bracket and provided with the aperture 26,and the verticallyadjustable block 27, below said aperture 26, of theleafsupporting arm 19, pivotally connected at its rear edge to theforward edge of the block 17 the leaf 20 upon the upper edge of thearni' 19, and the spring-pressed catch 22,

pivoted between its ends to the under side of the leaf20, to engage theblock 17 at its aperture with its forward end, the rear end of thecatch, when the parts are in position, being over and adjacent to theupper end of the sliding block 27, substantially as set forth.

3. The combination, with a support and a leaf hinged thereby to swingfrom a horizontal to a vertical position and from its vertical positionedgewise downward at right angles-to its other two positions, of anink-well secured to theforward part of the hinged end of the leaf andhaving atuhe' entering it at a pointncarest the forward longitudinaledge'and swinging or free-end of the leaf, and extending near itsbottom, whereby when the leaf is swung from 'a horizontal to a verticalpositionthe inkwill rest in "that end of the well nearest the hinged endof the leaf and when the leaf is turneddown edgewise at right a-nglestoits two former positions the ink will :rest in that end of the wellnearest the in ncr longitudinal edge-of the lea., substantially as setibrth.
